Hi All,

I am new in Elastic Search and

I want to use different fields like unique id.

For example:

I have a data elastic search document as follows :

\</\>@Document(indexName = "outlet")  
public class MyIndex implements IESMapper{

```
@Id
private String name;
private Long Id;
private Type type;
private String address;
private String geoLocation;
private String city;

// getter and setter methods

```

}\</\>

Is it possible Id, address, and geoLocation be unique indexes in the Elastic Search database?

I hope be clear,

Thanks a lot for some help

Silvia

The only field that is unique within an index is the id of the document. You can create a custom id based on several other fields, which would be unique, but there is no way to force any other indexed fields to be unique.
